Nissan Sentra Headlight Bulb Size

Additional Notes

• The H9 bulb is a single-filament halogen type rated at 12V and 65W, built to ECE standards with a PGJ19-5 base. Because it carries only one filament, it serves exclusively as a high beam source in the Nissan Sentra, requiring a separate bulb for the low beam function.
• The H11 bulb is also a single-filament halogen type, rated at 12V and 55W, with a PGJ19-2 base. Its lower wattage relative to the H9 reflects its role as a low beam source, where sustained operation and reduced glare take priority over peak output.
• The Nissan Sentra uses separate H9 and H11 bulbs for high and low beams respectively across the 2013-2023 model years, with the exception of the 2012 model year. Because the H9 and H11 share a similar physical form but have different base configurations, PGJ19-5 versus PGJ19-2, the two types are not interchangeable despite their visual resemblance.
• The 9008 bulb, also known as the H13, is a dual-filament halogen type rated at 12V with 65W for high beam and 55W for low beam. Its P26t base and dual-filament design allow a single bulb to serve both beam functions, which is reflected in the Sentra specifications for 2004-2012, where the same 9008 size is listed for both high and low beam positions.
• The 9007 bulb is a dual-filament halogen type rated at 12V with 65W for high beam and 55W for low beam, using a PX29t base. It is listed for both beam positions on the Sentra for 2000-2003, as well as for the 1999 late model. The 9007 and 9008 use different base configurations and are not interchangeable with each other.
• The 9004 bulb is a dual-filament halogen type rated at 12V with 65W for high beam and 45W for low beam, using a P29t base. The lower low-beam wattage of 45W distinguishes it from the 9007 and 9008, which both produce 55W on the low beam filament. The 9004 is listed for both beam positions on the Sentra across 1985-1998, with the exception of 1993-1994, as well as for the 1999 early model.
• The 1999 Nissan Sentra carries a within-year fitment split, with early production units using the 9004 bulb and late production units using the 9007. These two types use different base configurations, P29t for the 9004 and PX29t for the 9007, making them physically incompatible with each other's sockets.
• The 9003 bulb is a dual-filament halogen type rated at 12V with 60W for high beam and 55W for low beam, using a P43t base. It is listed for both beam positions on the Sentra for 1993-1994. The P43t base is a different fitting from those used by the 9004, 9007, and 9008 types.
• The H6054 is a rectangular sealed beam unit measuring 5 by 7 inches, operating at 12V under ANSI standards. Unlike all other bulb types in these specifications, the H6054 is not a replaceable capsule bulb; the entire sealed unit is replaced as a single assembly. It is listed for the Sentra for 1982-1984.
• The 2020 Nissan Sentra specifications carry a conditional note stating that the H9 high beam and H11 low beam sizes apply specifically to vehicles equipped with halogen capsule headlamps, indicating that not all 2020 Sentra units share the same headlamp assembly type.
